VB,NET to Wordpress Example

Been trying to wrap my head around manipulating a php wordpress install with a .NET client.

Not much clear cut info out there so I figured I would post a quick example to give those interested a starting point.

First things first.  You need the  CookComputing.XmlRpc library. You can download the latest version here.

You need to extract the zip file using winzip, winrar or another non system extractor. 

For some reason the bin directory is not visible if using the system extractor even if you are running as Admin and have all folder view options on.

Next, start up visual studio and create a new standard windows forms application.  You should not target a compact framework. I had problems with the .net 4 client profile framework so I changed the framework to standard .net 4.0

Now you will need to add two references to the project.  Click add reference from visual studio and select browse.  You need to browse to the bin directory of the xml-rpc.net.2.5.0 directory you previously extracted.  Add a reference to   CookComputing.XmlRpcV2.dll  and IStateName.dll

Go back to your form and add a single button. View the form code window and add the following.

Imports CookComputing.XmlRpc
Imports System

Public Class Form1 'your form name
    Public Structure category
        Public categoryId As Object
        Public parentId As Object
        Public description As Object
        Public categoryName As Object
        Public htmlUrl As Object
        Public rssUrl As Object
    End Structure
 '// important to have the correct wordpress xmlrpc.php path.  If in doubt, use your browser and navigate to it '//first.

 <XmlRpcUrl("http://yoursite.com/wordpress/xmlrpc.php")> _
    Public Interface IWP
        Inherits IXmlRpcProxy

        <XmlRpcMethod("wp.getCategories")> _
        Function getCategories(ByVal args() As String) As category()
    End Interface
'// your button1 code....
 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim proxy As IWP = XmlRpcProxyGen.Create(Of IWP)()
        Dim args() As String = {"http:/yoursite.com", _
                                  "AdminUserName", "AdminPassword"}
        Dim categories() As category
        categories = proxy.getCategories(args)
        For Each category In categories
            Debug.Print(category.categoryId)
            Debug.Print(category.categoryName)
            Debug.Print(category.description)
            Debug.Print(category.htmlUrl)
            Debug.Print(category.rssUrl)
        Next

    End Sub
End Class


That should do it.
